This wine is rapidly becoming one of the most interesting vineyard selections to emerge from the Montalcino appellation thanks to the cool microclimate and black slate-like soils of the site. The Castello Romitorio 2018 Brunello di Montalcino Filo di Seta is a wine of unique dimension and depth. It shows tart, almost crunchy red fruit and cassis, with background notes of cola, balsam herb, crushed stone and pencil shavings. The tannins need another two or three years to become silky. The wine ages in oak for 30 months, and production is limited to 7,300 bottles in this vintage.
